Investment guru Warren Buffet just opened an account with Twitter with the handle @WarrenBuffet, and he already has more than 188,000 followers in a matter of hours.

The chief executive officer of Berkshire Hathaway has so far two tweets, the first announcing his joining the popular microblogging site and the second is an invitation for followers to read his essay on why women are the key to America's prosperity.

The 82-year-old Oracle of Omaha is known to not even have a computer in his office and once admitted to now knowing how to check his voicemail. The Wall Street Journal said he was egged into finally joining social media by his friends at Fortune Magazine when he sat down for an interview on women and work.

Taking advantage of Mr Buffett's popularity in the business circle, the magazine is announcing the interview through social media.

This is the real Twitter account of Mr Buffett, although there are several fake ones with hundreds of thousands of followers. Among his followers are fellow billionaire and co-founder of Microsoft, Bill Gates, who retweeted the investment expert's joining the popular microblogging site.

Maybe Mr Buffett has learned his lesson the hard and expensive way, particularly his known aversion to technology, because a potential deal to bail our Lehman brothers collapsed when he failed to check the voicemail on his mobile phone because he didn't know how to.
